+ *       (c) You must retain, in the Source form of any Derivative Works
+ *           that You distribute, all copyright, patent, trademark, and
+ *           attribution notices from the Source form of the Work,
+ *           excluding those notices that do not pertain to any part of
+ *           the Derivative Works; and
+ *
+ *       (d) If the Work includes a "NOTICE" text file as part of its
+ *           distribution, then any Derivative Works that You distribute must
+ *           include a readable copy of the attribution notices contained
+ *           within such NOTICE file, excluding those notices that do not
+ *           pertain to any part of the Derivative Works, in at least one
+ *           of the following places: within a NOTICE text file distributed
+ *           as part of the Derivative Works; within the Source form or
+ *           documentation, if provided along with the Derivative Works; or,
+ *           within a display generated by the Derivative Works, if and
+ *           wherever such third-party notices normally appear. The contents
+ *           of the NOTICE file are for informational purposes only and
+ *           do not modify the License. You may add Your own attribution
+ *           notices within Derivative Works that You distribute, alongside
+ *           or as an addendum to the NOTICE text from the Work, provided
+ *           that such additional attribution notices cannot be construed
+ *           as modifying the License.
+ *
+ *       You may add Your own copyright statement to Your modifications and
+ *       may provide additional or different license terms and conditions
+ *       for use, reproduction, or distribution of Your modifications, or
+ *       for any such Derivative Works as a whole, provided Your use,
+ *       reproduction, and distribution of the Work otherwise complies with
+ *       the conditions stated in this License.
+ *
+ *    5. Submission of Contributions. Unless You explicitly state otherwise,
+ *       any Contribution intentionally submitted for inclusion in the Work
+ *       by You to the Licensor shall be under the terms and conditions of
+ *       this License, without any additional terms or conditions.
+ *       Notwithstanding the above, nothing herein shall supersede or modify
+ *       the terms of any separate license agreement you may have executed
+ *       with Licensor regarding such Contributions.
+ *
+ *    6. Trademarks. This License does not grant permission to use the trade
+ *       names, trademarks, service marks, or product names of the Licensor,
+ *       except as required for reasonable and customary use in describing the
+ *       origin of the Work and reproducing the content of the NOTICE file.
+ *
+ *    7. Disclaimer of Warranty. Unless required by applicable law or
+ *       agreed to in writing, Licensor provides the Work (and each
+ *       Contributor provides its Contributions) on an "AS IS" BASIS,
+ *       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+ *       implied, including, without limitation, any warranties or conditions
+ *       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+ *       PARTICULAR PURPOSE. You are solely responsible for determining the
+ *       appropriateness of using or redistributing the Work and assume any
+ *       risks associated with Your exercise of permissions under this License.
+ *
+ *    8. Limitation of Liability. In no event and under no legal theory,
+ *       whether in tort (including negligence), contract, or otherwise,
+ *       unless required by applicable law (such as deliberate and grossly
+ *       negligent acts) or agreed to in writing, shall any Contributor be
+ *       liable to You for damages, including any direct, indirect, special,
+ *       incidental, or consequential damages of any character arising as a
+ *       result of this License or out of the use or inability to use the
+ *       Work (including but not limited to damages for loss of goodwill,
+ *       work stoppage, computer failure or malfunction, or any and all
+ *       other commercial damages or losses), even if such Contributor
+ *       has been advised of the possibility of such damages.
+ *
+ *    9. Accepting Warranty or Additional Liability. While redistributing
+ *       the Work or Derivative Works thereof, You may choose to offer,
+ *       and charge a fee for, acceptance of support, warranty, indemnity,
+ *       or other liability obligations and/or rights consistent with this
+ *       License. However, in accepting such obligations, You may act only
+ *       on Your own behalf and on Your sole responsibility, not on behalf
+ *       of any other Contributor, and only if You agree to indemnify,
+ *       defend, and hold each Contributor harmless for any liability
+ *       incurred by, or claims asserted against, such Contributor by reason
+ *       of your accepting any such warranty or additional liability.
+ *
+ *    END OF TERMS AND CONDITIONS
+ *
+ *    APPENDIX: How to apply the Apache License to your work.
+ *
+ *       To apply the Apache License to your work, attach the following
+ *       boilerplate notice, with the fields enclosed by brackets "[]"

+ *       PARTICULAR PURPOSE. You are solely responsible for determining the
+ *       appropriateness of using or redistributing the Work and assume any
+ *       risks associated with Your exercise of permissions under this License.
+ *
+ *    8. Limitation of Liability. In no event and under no legal theory,
+ *       whether in tort (including negligence), contract, or otherwise,
+ *       unless required by applicable law (such as deliberate and grossly

+ *       work stoppage, computer failure or malfunction, or any and all
+ *       other commercial damages or losses), even if such Contributor
+ *       has been advised of the possibility of such damages.
+ *
+ *    9. Accepting Warranty or Additional Liability. While redistributing
+ *       the Work or Derivative Works thereof, You may choose to offer,
+ *       and charge a fee for, acceptance of support, warranty, indemnity,
+ *       or other liability obligations and/or rights consistent with this

+ *       of any other Contributor, and only if You agree to indemnify,
+ *       defend, and hold each Contributor harmless for any liability
+ *       incurred by, or claims asserted against, such Contributor by reason

+ *
+ *       "Derivative Works" shall mean any work, whether in Source or Object
+ *       form, that is based on (or derived from) the Work and for which the
+ *       editorial revisions, annotations, elaborations, or other modifications
+ *       represent, as a whole, an original work of authorship. For the purposes
+ *       of this License, Derivative Works shall not include works that remain
+ *       separable from, or merely link (or bind by name) to the interfaces of,
+ *       the Work and Derivative Works thereof.
+ *
+ *       "Contribution" shall mean any work of authorship, including

+ *       Contribution(s) alone or by combination of their Contribution(s)
+ *       with the Work to which such Contribution(s) was submitted. If You

+ *       cross-claim or counterclaim in a lawsuit) alleging that the Work
+ *       or a Contribution incorporated within the Work constitutes direct
+ *       or contributory patent infringement, then any patent licenses
+ *       granted to You under this License for that Work shall terminate
+ *       as of the date such litigation is filed.

+ *       (c) You must retain, in the Source form of any Derivative Works
+ *           that You distribute, all copyright, patent, trademark, and
+ *           attribution notices from the Source form of the Work,
+ *           excluding those notices that do not pertain to any part of
+ *           the Derivative Works; and
+ *
+ *       (d) If the Work includes a "NOTICE" text file as part of its
+ *           distribution, then any Derivative Works that You distribute must
+ *           include a readable copy of the attribution notices contained
+ *           within such NOTICE file, excluding those notices that do not
+ *           pertain to any part of the Derivative Works, in at least one
+ *           of the following places: within a NOTICE text file distributed
+ *           as part of the Derivative Works; within the Source form or
+ *           documentation, if provided along with the Derivative Works; or,

+ *       for use, reproduction, or distribution of Your modifications, or

+ *       agreed to in writing, Licensor provides the Work (and each
+ *       Contributor provides its Contributions) on an "AS IS" BASIS,

+ *       other commercial damages or losses), even if such Contributor
+ *       has been advised of the possibility of such damages.

+ *       of this License, Derivative Works shall not include works that remain
+ *       separable from, or merely link (or bind by name) to the interfaces of,
+ *       the Work and Derivative Works thereof.
+ *
+ *       "Contribution" shall mean any work of authorship, including
+ *       the original version of the Work and any modifications or additions
+ *       to that Work or Derivative Works thereof, that is intentionally
+ *       submitted to Licensor for inclusion in the Work by the copyright owner
+ *       or by an individual or Legal Entity authorized to submit on behalf of
+ *       the copyright owner. For the purposes of this definition, "submitted"
+ *       means any form of electronic, verbal, or written communication sent
+ *       to the Licensor or its representatives, including but not limited to
+ *       communication on electronic mailing lists, source code control systems,
+ *       and issue tracking systems that are managed by, or on behalf of, the
+ *       Licensor for the purpose of discussing and improving the Work, but
+ *       excluding communication that is conspicuously marked or otherwise
+ *       designated in writing by the copyright owner as "Not a Contribution."
+ *
+ *       "Contributor" shall mean Licensor and any individual or Legal Entity
+ *       on behalf of whom a Contribution has been received by Licensor and
+ *       subsequently incorporated within the Work.
+ *
+ *    2. Grant of Copyright License. Subject to the terms and conditions of
+ *       this License, each Contributor hereby grants to You a perpetual,
+ *       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+ *       copyright license to reproduce, prepare Derivative Works of,
+ *       publicly display, publicly perform, sublicense, and distribute the
+ *       Work and such Derivative Works in Source or Object form.
+ *
+ *    3. Grant of Patent License. Subject to the terms and conditions of
+ *       this License, each Contributor hereby grants to You a perpetual,
+ *       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+ *       (except as stated in this section) patent license to make, have made,
+ *       use, offer to sell, sell, import, and otherwise transfer the Work,
+ *       where such license applies only to those patent claims licensable
+ *       by such Contributor that are necessarily infringed by their
+ *       Contribution(s) alone or by combination of their Contribution(s)
+ *       with the Work to which such Contribution(s) was submitted. If You
+ *       institute patent litigation against any entity (including a
+ *       cross-claim or counterclaim in a lawsuit) alleging that the Work
+ *       or a Contribution incorporated within the Work constitutes direct
+ *       or contributory patent infringement, then any patent licenses
+ *       granted to You under this License for that Work shall terminate
+ *       as of the date such litigation is filed.
+ *
+ *    4. Redistribution. You may reproduce and distribute copies of the
+ *       Work or Derivative Works thereof in any medium, with or without
+ *       modifications, and in Source or Object form, provided that You
+ *       meet the following conditions:
+ *
+ *       (a) You must give any other recipients of the Work or
+ *           Derivative Works a copy of this License; and
+ *
+ *       (b) You must cause any modified files to carry prominent notices
+ *           stating that You changed the files; and
+ *
+ *       (c) You must retain, in the Source form of any Derivative Works
+ *           that You distribute, all copyright, patent, trademark, and
+ *           attribution notices from the Source form of the Work,
+ *           excluding those notices that do not pertain to any part of
+ *           the Derivative Works; and
+ *
+ *       (d) If the Work includes a "NOTICE" text file as part of its
+ *           distribution, then any Derivative Works that You distribute must
+ *           include a readable copy of the attribution notices contained
+ *           within such NOTICE file, excluding those notices that do not
+ *           pertain to any part of the Derivative Works, in at least one
+ *           of the following places: within a NOTICE text file distributed
+ *           as part of the Derivative Works; within the Source form or
+ *           documentation, if provided along with the Derivative Works; or,
+ *           within a display generated by the Derivative Works, if and
+ *           wherever such third-party notices normally appear. The contents
+ *           of the NOTICE file are for informational purposes only and
+ *           do not modify the License. You may add Your own attribution
+ *           notices within Derivative Works that You distribute, alongside
+ *           or as an addendum to the NOTICE text from the Work, provided
+ *           that such additional attribution notices cannot be construed
+ *           as modifying the License.
+ *
+ *       You may add Your own copyright statement to Your modifications and
+ *       may provide additional or different license terms and conditions
+ *       for use, reproduction, or distribution of Your modifications, or
+ *       for any such Derivative Works as a whole, provided Your use,
+ *       reproduction, and distribution of the Work otherwise complies with
+ *       the conditions stated in this License.
+ *
+ *    5. Submission of Contributions. Unless You explicitly state otherwise,
+ *       any Contribution intentionally submitted for inclusion in the Work
+ *       by You to the Licensor shall be under the terms and conditions of
+ *       this License, without any additional terms or conditions.
+ *       Notwithstanding the above, nothing herein shall supersede or modify
+ *       the terms of any separate license agreement you may have executed
+ *       with Licensor regarding such Contributions.
+ *
+ *    6. Trademarks. This License does not grant permission to use the trade
+ *       names, trademarks, service marks, or product names of the Licensor,
+ *       except as required for reasonable and customary use in describing the
+ *       origin of the Work and reproducing the content of the NOTICE file.
+ *
+ *    7. Disclaimer of Warranty. Unless required by applicable law or
+ *       agreed to in writing, Licensor provides the Work (and each
+ *       Contributor provides its Contributions) on an "AS IS" BASIS,
+ *       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+ *       implied, including, without limitation, any warranties or conditions
+ *       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+ *       PARTICULAR PURPOSE. You are solely responsible for determining the
+ *       appropriateness of using or redistributing the Work and assume any
+ *       risks associated with Your exercise of permissions under this License.
+ *
+ *    8. Limitation of Liability. In no event and under no legal theory,
+ *       whether in tort (including negligence), contract, or otherwise,
+ *       unless required by applicable law (such as deliberate and grossly
+ *       negligent acts) or agreed to in writing, shall any Contributor be
+ *       liable to You for damages, including any direct, indirect, special,
+ *       incidental, or consequential damages of any character arising as a
+ *       result of this License or out of the use or inability to use the
+ *       Work (including but not limited to damages for loss of goodwill,
+ *       work stoppage, computer failure or malfunction, or any and all
+ *       other commercial damages or losses), even if such Contributor
+ *       has been advised of the possibility of such damages.
+ *
+ *    9. Accepting Warranty or Additional Liability. While redistributing
+ *       the Work or Derivative Works thereof, You may choose to offer,
+ *       and charge a fee for, acceptance of support, warranty, indemnity,
+ *       or other liability obligations and/or rights consistent with this
+ *       License. However, in accepting such obligations, You may act only
+ *       on Your own behalf and on Your sole responsibility, not on behalf
+ *       of any other Contributor, and only if You agree to indemnify,
+ *       defend, and hold each Contributor harmless for any liability
+ *       incurred by, or claims asserted against, such Contributor by reason
+ *       of your accepting any such warranty or additional liability.
+ *

+ *
+ *       "Derivative Works" shall mean any work, whether in Source or Object
+ *       form, that is based on (or derived from) the Work and for which the
+ *       editorial revisions, annotations, elaborations, or other modifications
+ *       represent, as a whole, an original work of authorship. For the purposes
+ *       of this License, Derivative Works shall not include works that remain
+ *       separable from, or merely link (or bind by name) to the interfaces of,
+ *       the Work and Derivative Works thereof.
+ *
+ *       "Contribution" shall mean any work of authorship, including
+ *       the original version of the Work and any modifications or additions

+ *       subsequently incorporated within the Work.
+ *
+ *    2. Grant of Copyright License. Subject to the terms and conditions of
+ *       this License, each Contributor hereby grants to You a perpetual,

+ *       copyright license to reproduce, prepare Derivative Works of,
+ *       publicly display, publicly perform, sublicense, and distribute the
+ *       Work and such Derivative Works in Source or Object form.
+ *
+ *    3. Grant of Patent License. Subject to the terms and conditions of

+ *       (except as stated in this section) patent license to make, have made,
+ *       use, offer to sell, sell, import, and otherwise transfer the Work,
+ *       where such license applies only to those patent claims licensable
+ *       by such Contributor that are necessarily infringed by their
+ *       Contribution(s) alone or by combination of their Contribution(s)
+ *       with the Work to which such Contribution(s) was submitted. If You
+ *       institute patent litigation against any entity (including a
+ *       cross-claim or counterclaim in a lawsuit) alleging that the Work
+ *       or a Contribution incorporated within the Work constitutes direct
+ *       or contributory patent infringement, then any patent licenses
+ *       granted to You under this License for that Work shall terminate
+ *       as of the date such litigation is filed.
+ *
+ *    4. Redistribution. You may reproduce and distribute copies of the
+ *       Work or Derivative Works thereof in any medium, with or without
+ *       modifications, and in Source or Object form, provided that You
+ *       meet the following conditions:
+ *
+ *       (a) You must give any other recipients of the Work or
+ *           Derivative Works a copy of this License; and
+ *
+ *       (b) You must cause any modified files to carry prominent notices
+ *           stating that You changed the files; and
+ *
+ *       (c) You must retain, in the Source form of any Derivative Works
+ *           that You distribute, all copyright, patent, trademark, and
+ *           attribution notices from the Source form of the Work,
+ *           excluding those notices that do not pertain to any part of
+ *           the Derivative Works; and
+ *
+ *       (d) If the Work includes a "NOTICE" text file as part of its
+ *           distribution, then any Derivative Works that You distribute must
+ *           include a readable copy of the attribution notices contained
+ *           within such NOTICE file, excluding those notices that do not
+ *           pertain to any part of the Derivative Works, in at least one
+ *           of the following places: within a NOTICE text file distributed
+ *           as part of the Derivative Works; within the Source form or
+ *           documentation, if provided along with the Derivative Works; or,
+ *           within a display generated by the Derivative Works, if and
+ *           wherever such third-party notices normally appear. The contents
+ *           of the NOTICE file are for informational purposes only and
+ *           do not modify the License. You may add Your own attribution
+ *           notices within Derivative Works that You distribute, alongside
+ *           or as an addendum to the NOTICE text from the Work, provided
+ *           that such additional attribution notices cannot be construed
+ *           as modifying the License.
+ *
+ *       You may add Your own copyright statement to Your modifications and
+ *       may provide additional or different license terms and conditions
+ *       for use, reproduction, or distribution of Your modifications, or
+ *       for any such Derivative Works as a whole, provided Your use,
+ *       reproduction, and distribution of the Work otherwise complies with
+ *       the conditions stated in this License.
+ *
+ *    5. Submission of Contributions. Unless You explicitly state otherwise,
+ *       any Contribution intentionally submitted for inclusion in the Work
+ *       by You to the Licensor shall be under the terms and conditions of
+ *       this License, without any additional terms or conditions.
+ *       Notwithstanding the above, nothing herein shall supersede or modify
+ *       the terms of any separate license agreement you may have executed
+ *       with Licensor regarding such Contributions.
+ *
+ *    6. Trademarks. This License does not grant permission to use the trade
+ *       names, trademarks, service marks, or product names of the Licensor,
+ *       except as required for reasonable and customary use in describing the
+ *       origin of the Work and reproducing the content of the NOTICE file.
+ *
+ *    7. Disclaimer of Warranty. Unless required by applicable law or
+ *       agreed to in writing, Licensor provides the Work (and each
+ *       Contributor provides its Contributions) on an "AS IS" BASIS,
+ *       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+ *       implied, including, without limitation, any warranties or conditions
+ *       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+ *       PARTICULAR PURPOSE. You are solely responsible for determining the
+ *       appropriateness of using or redistributing the Work and assume any
+ *       risks associated with Your exercise of permissions under this License.
+ *
+ *    8. Limitation of Liability. In no event and under no legal theory,
+ *       whether in tort (including negligence), contract, or otherwise,
+ *       unless required by applicable law (such as deliberate and grossly
+ *       negligent acts) or agreed to in writing, shall any Contributor be
+ *       liable to You for damages, including any direct, indirect, special,
+ *       incidental, or consequential damages of any character arising as a
+ *       result of this License or out of the use or inability to use the
+ *       Work (including but not limited to damages for loss of goodwill,
+ *       work stoppage, computer failure or malfunction, or any and all
+ *       other commercial damages or losses), even if such Contributor
+ *       has been advised of the possibility of such damages.
+ *
+ *    9. Accepting Warranty or Additional Liability. While redistributing
+ *       the Work or Derivative Works thereof, You may choose to offer,
+ *       and charge a fee for, acceptance of support, warranty, indemnity,
+ *       or other liability obligations and/or rights consistent with this
+ *       License. However, in accepting such obligations, You may act only
+ *       on Your own behalf and on Your sole responsibility, not on behalf
+ *       of any other Contributor, and only if You agree to indemnify,
+ *       defend, and hold each Contributor harmless for any liability
+ *       incurred by, or claims asserted against, such Contributor by reason
+ *       of your accepting any such warranty or additional liability.
+ *
+ *    END OF TERMS AND CONDITIONS
+ *
+ *    APPENDIX: How to apply the Apache License to your work.
+ *
+ *       To apply the Apache License to your work, attach the following
+ *       boilerplate notice, with the fields enclosed by brackets "[]"
